Why non HD/Blueray players??
If $100 is your budget you should be able to(once again) get the Toshiba A2 HDDVD player for under $100. Watch the black Friday sales.
It does a good job at upscaling SDDVD's to 1080i. You won't see a difference between 1080i or p depending on the TV's upscaler.
Read the reviews at Amazon.
